Malin [5 7] ABSTRACT A multi-purpose landscaping implement able to perform simultaneous functions of rolling, raking, pulverizing, and leveling of soil attachable for use on a hydraulic shovel lift or the like of a landscaping vehicle. The amount of weight required for the rolling operation is reduced by using a portion of the weight of the working vehicle.

4 Claims, 3 Drawing Figures LANDSCAPING IMPLEMENT BACKGROUND OF THE INVENTION to properly prepare soil for planting, se eral different operations must be performed on the soil such as pulverizing, leveling, and rolling. In the past, these operations have been done independently using some mechanized means, such as a tractor, which required having several different pieces of equipment, each of which would be dragged behind the tractor during each operation. Also very heavy rollers were required to properly flatten the surface and pack it. Applicant's invention eliminates these problems by providing a multifunctional landscaping implement that is attachable to the shovel lift of a tractor and is able to perform the functions of pulverizing, leveling, and rolling with a reduced size roller. Forward operation is provided thus allowing better visibility for the tractor operator while performing the landscaping work.

BRIEF DESCRIPTION OF THE INVENTION A landscaping implement to be used in conjunction with a tractor hydraulic lift or the like having a roller means, a soil leveling means, and a rake shaped soil pulverizing means coupled together in line and joined by an I-beam supporting structure. When attached to and properly oriented with respect to the hydraulic lifting means, the implement can add the weight of the tractor to the roller or pulverizing means by orienting the lifting device so that the front wheels of the vehicle are raised above the ground and front load is supported on the implement. The implements angular orientation with the ground provides for pulverizing, grading, and rolling operations to be simultaneous performed in front of the vehicle, so that the operator can observe all these operations while at the same time maintaining control of the vehicle.

It is an object of this invention to provide a landscaping implement capable of simultaneously pulverizing, leveling, and rolling soil.

It is another object of this invention to provide a landscaping implement that may be attached to a shovel system commonly found in tractor vehicles and the like for controlling the landscaping implement.

It is yet another object of this invention to provide a landscaping implement used as a roller in which the vehicle weight can be used to increase the ground rolling pressure.

And yet still another object of this invention is to provide a landscaping implement that may be easily attached to the front of a landscaping vehicle which allows the operator the ability to look forward during landscaping operations while maintaining control of the vehicle.

And still yet another object of this invention is to provide for the simultaneous rolling, grading, pulverizing of the soil with a single control device.

In accordance with these and other objects which will be apparent hereinafter, the instant invention will now be shown with particular reference to the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING In the drawing:

FIG. I is a side prospective view showing applicants invention coupled to a tractor shovel.

FIG. 2 is a partial elevation of the roller support mechanism of applicants invention.

FIG. 3 shows a back prospective view of the main structural member of applicants invention.

PREFERRED EMBODIMENT OF THE INVENTION Referring now to the drawings, and especially FIG. 1, applicants invention is shown coupled to a representive tractor shovel 11. The shovel can be moved rotationally and horizontally and vertically by proper control of connecting arms 12a, 12b, and 14 in conjunction with hydraulic lift unit 13. During normal shoveling operations, applicants invention would not be coupled to the shovel 11. However when it is desired to pulverize, scrape, and roll a soil surface, applicants invention is coupled to shovel 11 by connecting braces 17. The connecting braces, only one side showing in FIG. I, are bolted to the shovel sides 11 in a standard manner. The basic structural unit of applicants invention is I-beam 15. Coupled to the I-beam are large spike-shaped teeth 16, their purpose being to plow and turn up the soil. In the center, an axle couples [beam 15 to long arms 20 rotatably about the middle section of I-beam. The opposite end of each arm 20 is rotatably coupled to a roller 21. In FIG. 1, the implement is shown in a rolling only position, the rake teeth 16 being above the soil. l-beam projecting member 15a acts as a scraping surface means for leveling pulverized soil. Thus, roller 21 accomplishes rolling while I-beam projecting member 15a performs scraping functions, and raking teeth to provide a raking function. I-beam member is sized so as to fit snuggly along its top edges shown in FIG. 1 underneath the shovel bottom. This allows for the firm coupling of the implement to the shovel. Supporting plate 17 is also bolted into the midsection of the I-beam on each side. Different adjusting holes may be provided in the I-beam center to allow for different sizes of the shovel width. The I-beam member is intended to be wider than the shovel width, thus allowing the supporting arms 20 to move freely without interferring with the shovel or coupling mechanism.

FIG. 2 shows a close-up of the roller supporting bar 20 and associated rotating axis 23 coupled to the I beam 15. The supporting structure of coupling bar 17 is not shown in FIG. 2 for simplicity. Welded to the top of the midsection of I-beam 15 is a cylindrical bar 23 that acts as an axle 23 which is rotatably coupled to a structure plate 22. Attached to structure plate 22 is the roller control arm 20 (one on each side) which allows roller movement around axis 23 as indicated by the arrows in FIG. 2. Above the roller control arm 20 and coupled to the front side of I-beam 15 is an upper limiting member 18 which prevents and limits the upward position of the roller support bar 20. Likewise, lower limiting member 19 prevents bar 20 from moving below the bottom edge of the I-beam 15. By limiting the travel of the roller control arm 20 between

stops

18 and 19, the shovel and consequently the I-beam 15 can be tilted by a hydraulic control system on a tractor or the like to provide different operating modes of the implement.

FIG. 3 shows the back portion of l-beam with the bracing teeth members 16 held by coupling bands 16a.

' The teeth may be attached to the bar in any standard manner that is well-known in the art, such as bolting, that would insure necessary strength for pulverizing and raking operations.

in operation, the implement may be used to provide individual rolling, raking, and leveling or scraping or any combination of these operations by providing the proper tilting angle and height of the shovel and consequently the l-beam member with respect to the soil surface and the roller support arms. For example, returning to FIG. 2, the shovel 11 could be positioned so that the raking teeth 16 protrude into the ground but tilted sufficiently so that surface 15a is not touching the soil. Also, the l-beam may be horizontally disposed of as shown in FIG. 2 with the spike teeth into the soil while scraping surface 15 is also leveling the top of the soil surface. Single rolling operation alone can be accomplished by raising the scraping surface of the raking teeth above the soil level and tilting the bucket downward thus causing arm to rotate in an upward direction until it is resting against stop 18. Continuing further downward force on the bucket 11 from the hydraulic control mechanism will cause the forward vehicle end to be lifted off the ground so that the entire forward vehicle weight will now be transmitted through the rolling device 20. This allows for the use of a lighter roller to achieve the same packing force pressure on the soil since the added weight of the vehicle on the forward can be positioned and thrust through this rolling surface. Also, by tilting the shovel and l-beam upwardly in the forward direction, the roller can be lifted entirely off the ground with the roller support arms 20 resting on stop 19 which will prevent arm 20 from rotating down to the ground level while at the same time allowing the teeth 16 to be employed in a raking pulverizing manner to loosen the soil.

The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
